Wormdrive Chainsaw: any ever been made?

mdvaden · 7th December 2007, 06:35 PM

In reading about chainsaws today - for fun - and it's like almost the most worn subject I've ever read - a question came to mind:

Has any manufacturer ever made a wormdrive chainsaw?

It's intriguing to think about anyhow.

Could have the starter rope in the back, and the engine could be positioned different.

Wonder what the possibilities or problems could be.

I don't know about worm drive but i've worked on some gear driven models they may have been slow but you couldn't bog them down.You could always look through Chain Saw Collectors Corner Home.

There are no worm drive to my knowledge.
rear handle already exist on old mac saw, mall saws and many more.
Clinton, PM(power machinery) and more have used belt driven system inside a dry case.
Homelite has a vast variety of old models using oil gear case.
Danarm have used a transversal engine with pressure plate and cork friction disk inside a casing filled with grade sae 90.

I collect old saws and have seen lots of technology but worm drive...this will need a bit of research.

So far, I just found a retrofit attachment. It's a chainsaw attachement for worm drive circular saws, for cutting beams.

Found a video of a guy cutting with something just like it on Youtube.

no oiler?looks like you'd go through alot of bars,chains,sprockets,and clutches.

the guy's around here spray wd-40 on the running chain before and during the cut.gotta watch what you use,it might stain the wood.but your right it is tuff on bar & chain.

At least they are not making many cuts. Our last home was fairly big, and it only had two wooden beams in the house. One in the basement, and one for the vaulted cieling upstairs. So that would have meant just 2 cuts, on a house where the builders probably spent 2 to 4 weeks getting the frame and main part of the building put in place.

Some framers just use a small chainsaw to do the same exact thing.

My guess is that the oiler is purposely avoided, to eliminate the risk of getting oil on the wood that would prevent primer and paint from sticking to the wood. They probably figure that wasting the piece of equipment after a certain number of cuts, is a reasonable cost of doing business.

From a mechanical engineering standpoint it is a bad idea. Modern chainsaws are direct drive and have 7 or 8 'teeth' on their directly mounted to crankshaft drive sprockets.

Worm drive is a technique used when large gearing reduction is needed and would result in extremely slow chain speed on a chain saw. Works well for a used car jack though.

yes it would be slooooow but you wouldn't ever stall it out.

OILERS...Hummmmmm......look at the pic and you will see how it was done in the old days.
This one was called a "keroba oiler" ......The device would be tied to a rope in a branche and filled with kerosene oil and would slowly drip on the chain.

Of course in those days everyone smoked cigarettes and cigar ....it was not a good idea to "puff one " after a cut.

And you have an Engineering Degree? Is that why your a tree monkey? ROFL.
